Dalí was a skilled draftsman, best known for the striking and bizarre images in his surrealist work. His painterly skills are often attributed to the influence of Renaissance masters. His best-known work, The Persistence of Memory, was completed in 1931. Dalí's expansive artistic repertoire includes film, sculpture, and photography, in collaboration with a range of artists in a variety of media.

Dalí attributed his "love of everything that is gilded and excessive, my passion for luxury and my love of oriental clothes" to a self-styled "Arab lineage," claiming that his ancestors were descended from the Moors.

Dalí was highly imaginative, and also had an affinity for partaking in unusual and grandiose behavior, in order to draw attention to himself. This sometimes irked those who loved his art as much as it annoyed his critics, since his eccentric manner sometimes drew more public attention than his artwork.
